It's a TSOP-48 chip, mounted to a SOIC-32 footprint via an adapter board. Not only would it be a huge pain to wire up, I don't have another TSOP test socket just lying around.

I don't know if what you listed covers this, but some of the only remaining game issues in higan-snes are special chip games running slightly faster or slower due to "cache delays" or whatever being unemulated. These issues are very minor and would be hard to detect in a blind comparison, but they're still worth fixing.

One noticeable example is SMW2's long intro that sort of desyncs over time. There's a scratching sound that's supposed to play when Yoshi looks at the map, but in higan it plays much later.
There is a similar issue in MMX2's attract mode (cx4 chip) where Mega Man dies in the attract mode because of unknown cache behavior.

It's been a few weeks with no replies, so I figured I'd check back. Any new tests to run?
